(Cl. 100-80) ABSTRACT OF THEDKSCLGSURE Laying down continuous spinning cable material in a containerby means of a mechanism performing traverse motions and compressing thematerial in one-half of the movable container each time after a doublelayer of the spinning cable material is laid down.

The present invention relates to a device for laying down continuousspinning cables.

In devices for laying down continuous spinning cables it is importantfor the following uninterrupted processing thereof that the spinningcable is laid down into a container in a very uniform manner. Thisproblem was solved by laying down devices performing traverse motions.The operation is generally carried out in such a manner that twotraverse motions are performed in perpendicular direction to oneanother, which motions are performed in one direction by the container,and in the other direction by the charging funnel, or both motions areperformed exclusively by the charging funnel or exclusively by thecontainer. To attain an economic filling weight, the material iscompressed each time after several layers thereof have been laid down,which operation has hitherto partly been performed manually, but partlyalso by machines.

In devices for laying down continuous spinning cables known hitherto,the laying down process is thus interrupted during the process ofmechanic compression. A continuous operation, therefore, necessitates anintermediate laying down of the spinning cable. The drawback of theintermediate laying down consists in that the resulting intervals in thelaying down process must be compensated by a high laying down speedwhich adversely affects the laying down process, especially if theproduction plant operates at a high speed as it is necessary, forexample, in the production of synthetic fibers. The material can be laiddown intermediately, for example, into the pressure piston constructedin the form of a container and provided with a hinged bottom. Thedrawback of this mode of operation consists in that there easily occurirregularities when the material, which has been laid downintermediately, slides down.

When working according to the process for laying down continuousspinning cables according to the invention in which there are at firstproduced Zigzag layers of the spinning cable in known manner by means ofmechanisms performing traverse motions, which layers are thencompressed, the aforesaid drawbacks are avoided by compressing thematerial in one half of the container each time after a double layer ofthe spinning cable has been laid down while in the other half of thecontainer the laying down process goes on continuously.

The advantage of the working method according to the device of theinvention consists in that the spinning cable is laid down in a moreuniform manner which results in a more economic filling weight.Moreover, fewer minders are required for carrying out the laying downprocess.

Another advantage of the device of the invention is that also cables ofa large width can be compressed automatically.

The device of the invention consists of a charging funnel which performstraverse motions perpendicular to the direction in which the spinningcable passes through the funnel, a movable container which performstraverse motions in perpendicular direction thereto and two pressurepistons disposed at both sides of the charging funnel whose pressuremotions are coupled with the container performing traverse motions insuch a manner that the pressure motions take place after each traversemotion of the container has been completed. It is advantageous toprovide the pressure pistons with deflector bars at the side at whichthe material issues from the charging funnel so that the material to belaid down cannot get on the pressure piston. The width of the pressurepiston shall exceed half the width of the container, that is to say itshall amount preferably to to of the width of the container so that theareas of compression overlap in the middle of the container.

The attached figure shows, as an example of an embodiment of theinvention. In this figure, the laying down device consists of a chargingfunnel 1 which performs traverse motions perpendicular to the directionof travel of the cable and which lays the cable 2 issuing from thefunnel down, layer on layer, over the whole length of the container. Thecontainer 3 placed on an interchangeable cart is moved transversely tothe direction of travel of the cable. This ensures that the spinningcable is distrib uted uniformly over the whole width of the container.

Above the container two pressure pistons 4 are disposed in such a mannerthat the charging funnel 1 can perform motions between the pressurepistons. The width of the piston is adjusted to the width of thetraverse motion of the container. in each final position of the motionof the container, a pressure piston 4 is introduced into the container 3for compressing the material. The areas compressed by the two pressurepistons overlap. The pres sure pistons 4 are provided with deflectorbars 5 at the side at which the material issues from the charging funnelso that the material cannot get on the piston during the process ofcompression. The control of the motions of the pistons is coupled withthe motion of the container and locked in such a manner that during theprocess of compression the motion of the container is discontinued. Inorder to avoid accidents the device is provided with a protective hood6. When this hood is raised (for example, when changing the container),the traverse motion of the container and, thereby, the pressure deviceare put out of operation.

The device according to the present invention cannot only be used forspinning cables made from different synthetic filamentous materials suchas polyesters, polyamides, polyolefifines, polyacrylonitrile and thelike, but also for laying down other materials in the form of cables orbands.
